Reclusive Calvin and Hobbes creator Bill Watterson returned to the comics page for the first time since the end of 1995 as a guest artist for three installments of the Pearls Before Swine comic strip by Stephan Pastis. The strips feature middle panels by Watterson in an arc that sees a young girl named Libby replace Pastis as artist. The strips featuring Watterson’s art were published on June 4th, 5th, and 6th.
